I am having the same problem with the beta release, now I am getting a problem that half way thru a print it stalls out and quits printing. I can pause it, and the machine returns to home, I am also able to load and unload filament. But when I resume print it goes back to the same exact spot and stalls again(no axis movement and no filament feed). Lastly if I try to use the custom settings after one or two files converted it starts going crazy on prints(finish is horrible,backlash is terrible, and when it go to wait position it hits that spot and tries to print without the head being heated. Any suggestions???
